write the balanced equation:
2H2O2>>2H2O + O2
how many moles of H2O2 is in 3.4 g?
molesH2O2=3.4/34=.1moles
so with the mole ratio in the balanced equation, you get half that of O2, or .05 moles O2
How many moles of oxygen are produced from the decomposition of 3.4g of hydrogen peroxide?
How many molecules of O2 are produced?

2H2O2 ==> 2H2O + O2
How many moles do you have in 3.4 g H2O2?
3.4/molar mass H2O2 = approximately 0.1.
You get 1 mol O2 for every 2 mol H2O2.
To convert to molecules, remember that there are 6.02E23 molecules in 1.0 mol.
